Development of an innovative reusable terahertz biosensor platform integrated graphene and all-silicon groove for detecting cancer cells in aqueous environments.
The label-free detection and analysis of cancer cells using portable biosensing devices is crucial and promising. In this study, a novel reusable biosensing platform with a microfluidic-like based on terahertz plasmonic metasurfaces utilizing graphene integrated with an all-silicon groove for detecting liquid live cancer cells was developed. The proposed biosensor platform stands out because it can differentiate between the concentrations of three types of cancer cells by monitoring changes in resonance intensity and phase difference. The minimum concentration for identification was reduced to as low as 5 × 104 cells/mL. We effectively constructed two-dimensional optical intensity cards using continuous wavelet transforms, which presented a more accurate approach for the recognition and determination of the three types of cancer cells. Our proposed biosensors show great potential for the determination and recognition of label-free cancer cells in aqueous environments as alternatives to non-immune biosensing technology.
期刊介绍：
Talanta provides a forum for the publication of original research papers, short communications, and critical reviews in all branches of pure and applied analytical chemistry. Papers are evaluated based on established guidelines, including the fundamental nature of the study, scientific novelty, substantial improvement or advantage over existing technology or methods, and demonstrated analytical applicability. Original research papers on fundamental studies, and on novel sensor and instrumentation developments, are encouraged. Novel or improved applications in areas such as clinical and biological chemistry, environmental analysis, geochemistry, materials science and engineering, and analytical platforms for omics development are welcome.
Analytical performance of methods should be determined, including interference and matrix effects, and methods should be validated by comparison with a standard method, or analysis of a certified reference material. Simple spiking recoveries may not be sufficient. The developed method should especially comprise information on selectivity, sensitivity, detection limits, accuracy, and reliability. However, applying official validation or robustness studies to a routine method or technique does not necessarily constitute novelty. Proper statistical treatment of the data should be provided. Relevant literature should be cited, including related publications by the authors, and authors should discuss how their proposed methodology compares with previously reported methods.
